Embodiment 1

[0021] see Figure 1-4 , in the embodiment of the present invention, a kind of grafting device for the breeding of Du pear dwarf anvil, comprises fixed ring 1, and clamp block 2 is arranged in described fixed ring 1, and hinge shaft-3 is arranged on the outer wall of clamp block 2, The hinged shaft-3 is hinged with the hinged rod 4, and the left and right side walls in the fixed ring 1 are provided with a chute 6, and a slide block 7 is slidably installed in the chute 6, and the slide block 7 is hinged with the end of the hinged rod 4, and the A spring 8 is arranged between the hinged rods 4, and the short anvil of Du pear is placed between the clamp blocks 2, and by the elastic force of the spring 8, the slide block 7 is moved toward each other, and then the clamp block 2 is moved to the middle, and the short anvil of Du pear is The anvil is clamped and fixed, and when the dwarf anvil of Du pears grows thicker, because of the spring 8 has a certain elastic force, the clamping...

Embodiment 2

[0028] In order to prevent the clamp block 2 from scratching the dwarf pear anvil, this embodiment is further improved on the basis of embodiment 1. The improvement is: the inner wall of the clamp block 2 is provided with a protective pad 28, and the anti-slip pad 28 , can protect the dwarf pear anvil, prevent it from being scratched and affect its growth; the material of the protective pad 28 is not limited, in the present embodiment, preferably, the material of the protective pad 28 is rubber.

[0029] The working principle of this embodiment is: in order to prevent the clamp block 2 from scratching the dwarf pear anvil, a protective pad 28 is provided on the inner side wall of the clamp block 2, and the dwarf pear anvil can be protected by the anti-skid pad 28. , to prevent it from being scratched and affecting its growth.

[0030]To sum up, by setting the spring 8, the Du pear anvil is placed between the clamping blocks 2, and the elastic force of the spring 8 makes the sl...

Abstract

The invention discloses a grafting device for pyrus betulaefolia dwarf stock breeding. The grafting device comprises a fixing ring, wherein clamping blocks are arranged in the fixing ring, first hinge shafts are arranged on the outer side walls of the clamping blocks, hinge rods are hinged to the first hinge shafts, sliding grooves are formed in the left side wall and the right side wall in the fixing ring, sliding blocks are installed in the sliding grooves in a sliding mode and are hinged to the tail ends of the hinge rods, and springs are arranged between the hinge rods. According to the grafting device, the springs are arranged, a pyrus betulaefolia dwarf stock is placed between the clamping blocks, the sliding blocks move oppositely through the elastic force of the springs, then the clamping blocks move towards the middle to clamp and fix the pyrus betulaefolia dwarf stock, and when the pyrus betulaefolia dwarf stock becomes thicker due to growth, the clamping blocks can move outwards due to the fact that the springs have certain elastic force, and normal growth of the pyrus betulaefolia dwarf stock is guaranteed.

Description

technical field [0001] The invention relates to the field of grafting devices, in particular to a grafting device for breeding dwarf pear stock. Background technique [0002] Grafting is one of the methods of artificial propagation of plants. That is to graft the branch or bud of one plant to the stem or root of another plant, so that the two parts connected together grow into a complete seedling. The grafting method is divided into branch grafting and bud grafting. Grafting is carried out by taking advantage of the healing function of plants after injury, and saponins are often used in the process of cultivation. [0003] When the existing grafting device for the selection of the dwarf pear stock is used to clamp the dwarf pear stock, it is easy to completely fix the dwarf pear stock, but the dwarf pear stock will become thicker due to natural growth, and the clamping device will Restricting the growth of the dwarf stock of Du pear will cause certain damage to it, which h...
